To all whom it may concern.-

Be it known that we, WILLIAM DOUGLAS ZERFFI and FREDERICK GEORGE RIEDEL,subjects'of the Queen of Great Britain, residing at Stockport, in thecounty of Chester, England, have invented certain new and usefulImprovementsin the Manufacture of For or Wool Hats, of which thefollowing is a full, clear, and exact description.

The invention relates to the manufacture of gentlemens fur or wool hatswith a view to producing different colors on different parts thereof. Thus we propose to make the inside of a different color from the outside,whereby we obviate the necessity for a lining,and there by make the hatlighter in weight than a lined hat and more attractive in appearancethan the ordinary unlined hat. We obtain these results in the followingmanner, the details of which may, however, be varied according to theeffect desired to be produced.

In order to obtain a light-colored insideto a black felt hat, we takethe proofed hatbodies that have already been dyed black with any of theordinary anilin-blacks and treat the part required to be of a lightershade than the others in the following manner: We make a causticsolution, which may be composed of the following chemicals and materialsor their equivalents in about the proportions stated: two pounds of tinsalt, one pound acetic acid, and one pound acetate-of-soda crystals. Tothe above we add the whole of the following solution, composed of fourpounds acetic acid, eighteen pounds water, and four pounds wheat-starch.The whole of the above are well mixed together and form a paste withwhich the parts of the hat which are required to be of a lighter shadethan the others are brushed over. After this the hatbodies are subjectedto steam in a steamingchest for a period of about twenty-five to thirtyminutes. They are then washed out in cold water. The parts of thehat-bodies that have been so treated are now of a clear light shade,while the other parts retain their original color, and the hat-bodiesthus treated are now ready for blocking and finishing in the ordinaryway.

In order to produce a variety of shades in the insides of hats, we addto the first dyebath dyestuffs (such as alizarins, 850.) which are notaffected to the same extent by the caustic solution.

We would here remark that we do not confine ourselves to the precisedetails herein given for imparting two different colors or shades tohat-bodies by the process of dyeing, as such may be varied withoutdeparting fromthe peculiar character of our invention.

Inthe accompanying drawing, illustrating our invention, we have shown inconventional form a derby hat half in elevation and half in section.

In the drawing the exterior of the crown (marked a) and the under andupper surfaces of the brim (marked, respectively, a and a are of thesame colorsay black-while the inside of the crown (marked 6) is of adifferen colorfor example, light brown.
